T 0 [LZZ whom 1 25 may concern:

Be it known that we, hIARlIN H. DOOLY and John D. OCALLAGHAN, citizensof the United States, residing, respectively, at At lanta, Fultoncounty, Georgia, and Chattanooga, Hamilton county, Tennessee, haveinvented certain new and useful Improvements in Car-Axle Lubricators, ofwhich the followin g is a specification, reference being had therein tothe accompanying drawings.

Our invention relates to improvements in journal-box lubricatorsdesigned especially for railroad-cars, and has for its object to providea slow feed of oil or lubricating material to the journal, to stop thefeed when the box is opened, and to prevent the entrance of dust to theinterior of the box.

In describing the device reference is had to the annexed drawings, inwhich Figure 1 represents a perspective view of the box with lubricatorattached; Fig. 2, a longitudinal section, and Fig. 3 a perspective view,of the brass, which is constructed of two pieces, one being a cover, theother the brass proper.

The box A has a flange or enlargement, B, to one side. Pi voted to thisfiangeBby means of a springsurrounded collar, C, and bolt or screw is adoor, D, swinging through an are relatively vertical. On the door is areceptacle or chamber, E, for oil or other lubricating material. Thechamber E is preferably cylindrical, and has a flattened base restingwhen the door is closed on top the box A, a flange, F, on the said topprojecting laterally into a recess at the junction of the door properand the oil-chamber. A similar flange, G, forms a stop on which reststhe bottom of the door when closed. These flanges normally retain thedoor, necessitating the movement outward of said door before it can beswung on the pivot, the spring-surrounded collar 0 allowing the saidmovement.

On top the chamber is an orifice surrounded by an annular shoulder. Theorifice is normally closed by a plug, H, havingalongitudinal hole partlythrough it. \Vithin this hole rests one end of a pin, I, the other endbeing shouldered, and from thence tapered to or nearly toancedle-point,which extends through a lug or teat,'K, on the flattenedportion of the oil'chamber, said lug when the door is closed passinginto a hole or orifice through the top of the box.

In Fig. 3 is shown the brass, made of two piecesa main piece, L, ofbrass, and acover, M, of cast-iron or other material. The brass L restson the spindle N of the car-axle, and is provided on top with alongitudinal fiattened rib, O, on each side of which are grooves P,extending nearly to the ends of the said brass, and have short grooves Rleading from them to the edge of the said piece L.

Projecting from one end of the brass L a eupshaped tongue, S,communicating with the grooves P. hen the door is closed, the end of theneedle-valve I rests within this cup, and is pressed sufficiently fromits seat to allow the oil to feed to the brass in small quantities, butwith a steady flow. The direct action of the valve is automatic.

From the grooves P are small passages T, leading to the spindle, andalso through the end of the brass to the shoulder on the spindle, whichprevent longitudinal movement of the same. The feed is to the saidshoulder directly to the top of the spindle and down the sides of thebrass to the sides of the spindle.

The cover M has a longitudinal groove for the reception of the rib O, bymeans of which lateral motion of the said cover is obviated, and lugs U,which engage over the end of the brass L and prevent longitudinalmovement.

A recess, V, corresponds with the tongue S, to allow the needle-valveand its casing to rest within the same, and also prevent the escape ofthe oil, the cover resting over the sides of said tongue. 7

Ribs on the sides of the brass L prevent the engagement of the entiresides of the same with the sides of the box A, and thus allow the oil tofreely flow to the journal.

The rear of the box A is provided with a receptacle for the slides W,the lower one resting on a spring, X, and each beveled at theircontiguous ends, so as to overlap and lock, the slides being providedfor the purpose of preventing the entrance of dustinto the box.

We claim- 1. A journal-box having its door provided with alubricator-reeeptacle, which has a hoe die-valve extending through a lugor teat on said receptacle, said teat passing into the box through ahole or orifice therein, substantially as and for the purpose specified.

2. A journal-box having a door provided with a lubricater-receptacle andfeeder, which consists of a receptacle proper, with an extended lug orteat, a needle-valve operating in said teat, anda recessed plug normallyclosing an orifice in said receptacle and receiving one end of thevalve, substantially as and for the purpose specified.

3. A journal-box having its door provided with a lubricator and pivotedat one side, said door being provided with a "slot, in which
